Electrical Conductivity of Semiconductors | Temperature dependence

[@sandhyam5528]

Thank you very much ma'am

I have small question ma,am on this beautiful presentation of the topic. Please tell me which variation of resistivity is right expression, out of r(T) = r(0)[1+a(T)] or the exponential one which you presented in this lecture. Thank you.

In which book can we get this derivation from?
